T o all whom it may con-cem:

Be it known that we, J oHN C. Wnrrninon and J Aoo C. LARsEN, citizens of the United States and Denmark, respectively, and residents oi Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful lmprovements in Brake- Hanger Supports for Trucks; and we do hereby declare the following to clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relatesvto an improvement in brake hanger-supports for trucks an particularly six wheel trucks, and is designed particularly as an improvement on the construction shown in patent to Larsen No. 1,298,228 dated March 25th, i919. r

ln the Larsen patent the brake hanger sup Orts are secured to a bracket on a shelf, the shelf and' bracket being cast integral with the bolster spring seats. With the Larsen improvements the truck side frames are necessarily made for right and left hand sides and the construction is such that the bolster opening cannotbe made to receive a holster having integral column guides.

The object of the invention is to provide a construction that eliminates the necessity for right and left hand patterns for the side frames; makes possible the use of the regular side frame constructionat the bolster openings so as to permit the use of bolster with integral or ixed column guides, and greatly simplifies the operation ot casting the side Jframes.

With these objects in view, our inventhe details of construction as'willbe more fully described and pointed out, in the claims.

ln the accompanying drawings, Figure 1 is a view in plan showing one side ot' a truck, part of the other side being broken away; Figure 2 is a View partly in end elevation and partly in section of the truck; Figure 3 is a view in transverse section on the line 3 3 of Figure 1 and Fi re 4 is a similar view on the line 4--4 of igure 1.

rlhe 'invention is applicable Jror use with various types of six wheel trucks, and while we have illustrated this improvement in connection with the side frames used in truck design, patented to Larsen and J ohnbe a full,

d each bolster 11 son No. 1,253,842 dated January 15th, 1918, We have done so for the purpose of illustration only and not with the intention of limiting its application to such side frame or any other particular construction of'side frame.

6 represents the 'truckside trames'. there being two to each side, with their adjacent ends overlappin as shown in Fig. 1, or the connection igherewith of the frames 7 carrying the bearings for the center axle 8. Each side frame 6 has a bearing for a journal of anend axle, and each is also provided with an opening 10 for the reception of one end of a transverse or auxiliary bolster 11, being yieldingly supported adjacent its ends, i in the openings 10. rlhe transverse holsters 11 are located as shown, .one between the front and middle axles, and the other between the rear and vmiddle axles, and support the longitudinal holsters 13, each of the latter having bearing at its ends on the transverse holsters 11, between the shoulders 14 on the latter as shown in Fig. 1, and each of said longitudinal holsters 13 is provided with the shoulders 15, which prevent their endwise movement on the transverse bolster 11.

rl`he main bolster 16, is in the present instance, located over the central axle 8, and is supported at its opposite ends in openings in the two longitudinal holsters 13 (see Fig. 2), and-is held against endwise displacement by theshoulders 18 as shown yin Figure 3 which, bear against the inner faces of the longitudinal holsters 13. With this construction the weight of the center bolster 16 and the load thereon, will be sufficient to retain the holsters in position without further securing devices other than the shoulders or lugs previously referred to.

The bolster openings 10 in the 4side frames are widened at the bottom as shown in Figure 2 to permit the bolster 11 having integral column guides 111L therein to be entered at the bottom and when elevated and seated on the springs 12, these column guides 11iL embrace the side walls of the openings-10 above the widened part of the latter and are thus held against endwise movei'nentl and o erate to prevent any spreading of the side frames.

Secured within the bolster openings 10 in the side frame and at the bottoms of sald on springs 12 seatedrwith- 'bolster 11 has been assembled, and after they haveA been secured they form the seats for the bolster carrying springs l2 which assist in holding the seats 19 in position. These bjrackets 20 extend inwardly horizontally in a plane slightly above the spring seats 19 and are located in a plane between the wheels as shown in Fig. 2 and form supports for the brake hanger' brackets 21 which are cast integral with the spring seats 19.

With thi's construction it will be seen that by using a spring seat carrying brackets forl the brake hangers, made separate from the side frames, the latter can be constructed with bols'teJry openings to :receive bolsters having fixed or integral column guides and the spring seats secured in place after the bolsters have been assembled, and it alsov eliminates the use of right and left hand patterns for the side frames.

lt is evident that many slight changes might be resortedl to in the relative arrangement of parts shown and described without departing from the spirit and scope of our invention. Hence we would have it un- Y 'derstood that we do not Wish to confine ourselves to the exact construction and arrange ,ment of parts shown and described, but

Having fully described our invention what we claim as new anddesire to' secure by Letters-Patent, is

1. In a railway truck., the combination of a side frame having a bolster opening, a spring seat removably secured to the side frame at the base of said opening and a brake hanger support carried at the inner edge of said spring seat.

2. In a railway truck, the combination of a side frame having a'bAo-lster .opening and a combined spring seat and brake hanger support separate from and secured to said side frame at the bottom of the bolster opening, thebrake hanger support projecting inwardly and upwardly from the seat.

3. In a railway truck,' the combination of aside frame having` a bolster opening and a spring seat separate from and secured to the side frame Within the bolster opening, the said spring seat having an integral inwardly projecting brake hanger support. In testimony whereof, We have signed this specification in the presence of two subscribing witnesses.
